Why does this tubular tire that was supposedly designed with Cyclocross in mind have recommended inflation pressure of 30-90 PSI? Most cyclocross tubular tires will be run with pressures in the mid 20s to mid 30 PSI.

Due to vittorias having a high tpi, they are very supple. So at lower pressures like common for cross tubs, these will get punctures. When riding them at the recommended pressure they will feel a lot lower in pressure because of how soft and supple they are.
